Hak-Seung Ro, Hae-Gwang Jeong, and Kyo-Beum Lee, "Torque Ripple Minimization of Switched Reluctance Motor Using Direct Torque Control Based on Sliding Mode Control," in Proc. ISIE Conf., May 2013, pp. 1–6. > Paper

This paper presents a robust direct torque control (DTC) combined with sliding mode control (SMC) for a switched reluctance motor

(SRM). The conventional method to control the torque ripple utilizes torque sharing function (TSF) considering the torque and motor

parameters. However the control method using TSF has the problem of unexpected torque ripple which is induced by the inner

inductance of the motor and the variable parameters. To overcome this problem, in this paper, DTC using SMC is derived. Unlike the

torque ripple control using TSF, the proposed method has simple and robust performance. The effectiveness of the proposed

algorithm is verified by simulation based on a 1.5kW SRM drive system.
